ABSTRACT:
Inflation apparatus for inflating a dilatation balloon of a catheter includes a frame having a first receiver supporting the barrel of a syringe. An operator has a second receiver supporting the plunger of the syringe. The syringe includes a fluid port for connecting the syringe chamber to the lumen of the catheter. A motor is supported by the frame and operatively connected to the operator to move the piston to change fluid pressure within the syringe chamber. A release device permits quick release of the pressure in the balloon catheter without the use of the motor. A pressure sensor is mounted to the frame to measure the pressure in the chamber through a diaphragm on the syringe. The pressure sensor operates a microprocessor-controlled display, which provides display of inflation and duration information and calculates other information. A circuit selectively operates the motor. An inflation control connected to the circuit permits operation of the motor at selected rates of inflation/deflation or to selected specific inflation pressures.
